The heat of the reflector represents wasted energy, so does the heat off an LED ballast... but it is much less. The shape of the reflector certainly may make a difference but it still gets hot...this is energy wasted plain and simple.

I think the point he was trying to make was that the LEDs internal reflector and the external reflector on a MH are pretty much the same. They both end up wasting a significant portion of the devices output.

Something to keep in mind:
In the case of the MH, a portion of that radiant energy that heats the reflector is IR (and a small amount of UV). With the LED, MOST of the radiant energy that HEATS the back of the LED die (the reflector and diode junction) is (was ) VISIBLE.

From the 84 articles i've read about this stuff( of the future) is that its not tested enought to determine the effects on your corals. It looks good, its flexible, lots of good features, a bit less heat but put your hand on a 1w LED after a minute you can't hold it, so it does have heat 30% less but enough. It does penetrate 36" from the last generation " i " But price wise i'm waitting for generation "P" when all the bugs are out, price are down, and the effects over a few years are known. Besides , Solaris production has been moved from China to the US, too many defects from China. Wait and see; there's no future like the past.

different connections. I did that and still the problem was not corrected. I asked to charge my credit card and send me a replacement, main unit only, as the problem was not in the ballast. Then when the defective unit was returned to credit my credit card. Was told that they could not do that! I worked the problem! Got my credit from
